DTC Descriptor

DTC B3060 00
- Unprogrammed Transponder Identification Code Received Malfunction

Circuit/System Description

When a keyless entry transmitter is inserted into the transmitter pocket/slot and the ignition mode switch is pressed, the transponder embedded in the transmitter is energized by the immobilizer antenna exciter coil. The transponder transmits a signal to the Body Control Module (BCM). The BCM then compares this value to a value stored in memory. If the value is correct, the BCM will send the prerelease password via the serial data circuit to the Engine Control Module (ECM). If the learned key code does not match or a transponder value is not received, the BCM will send the start disable password to the ECM.

Conditions for Running the DTC

Ignition is in the Accessory or Run position.

Conditions for Setting the DTC

The transponder value measured by the BCM is incorrect or not learned to the vehicle.

Action Taken When the DTC Sets

* Vehicle starting will be disabled.

* The security indicator in the instrument cluster will be illuminated. The driver information center will display a service message.

Conditions for Clearing the DTC

* A current DTC will be cleared when the BCM detects a valid transponder value from the transmitter.

* A history DTC will be cleared after 100 malfunction-free ignition cycles or when a scan tool is used to clear DTCs.

Circuit/System Verification

1. Perform the Replacing Transmitters procedure. Refer to Remote Control Door Lock and Theft Deterrent Transmitter Programming Testing and Inspection.

2. Verify the K9 Body Control Module learns the transmitter. The scan tool Master Keys Learned parameter should increment to indicate another key has been learned.

• If the K9 Body Control Module does not learn the transmitter
Replace the appropriate transmitter.

• If the K9 Body Control Module learns the transmitter

3. All OK.
